IMPROVEMENT IN ODORLESS CLOSETS.

Specification forming part of Letters Patent No. 184,099, dated November 7, 1876; application filed September 21, 1876.

To all whom it may concern Be it known that I, GEO. R. MOORE, of the city and county of Philadelphia, in the State of Pennsylvania, have invented new and useful Improvements in Odorless Closets, which improvements are fully set forth in the follow- The accompanying drawing, in transverse vertical section, shows such a vault, D, with all needful devices for its successful operation duly combined. Of course this vault should be made of suitable materials, and of any size or shape desired. A is a hinged seat, in due form for privy use. There may be a supple mental lid hinged also to this, if desired. A is a short conducting pipe or throat within andsmaller than themain conducting-pipe B, so that an air-space, 0, exists between the two. B extends from the seat A to near the bottom of the vault D, so that a small quantity of water poured into it will make a depth sufficient to constitute a trap for air, and thereby cut off all interchange of the internal air of thevault with the external. Though in this instance the pipe B is straight and vertical, any shape, direction, or distance is practicable aslon g as the privy-seat is high enough to afl'ord a descent to the vault; also, any nuim ber of pipes from other seats may be conducted either directly to the vault or indirectly by branching into B. E is division-plate or kind of strainer, to keep floating paper or other like materials from obstructing the passage of fluid matter out through the cock h, if at any time it is desired to use the cock for the purpose of reducing the quantity of liquid which the vault may contain. Gr shows a removable lid, closing an aperture which may be used in cleaning the vault. A valve may also be used in'conjunction with it, if desired. H is an air-pipe from the vault to the chimney K. It is under the control of the cock I. J is an air-pipe from the annular air chamber O to the chimney K. L shows a fire-grate, which may be used in burning fuel to heat the airpipe J, so as to give a draft through it, and thus a current of air down the throat A, and on in the direction shown by the arrows. M is a gas-burner, for use, if desired, in burning gas to heat the air-pipe. Of course any mechanical means of producing a current of air is the same in eifect; and, besides, it is presumed that the ordinary smoke chimneys will be sufficiently heated by their customary use, so that nothing further will be required in ordinary cases. N is a door to afford access to the grate and to the gas-burner in the chimney.

It will be readily seen no interchange of air between the vault and the room in which the seat A is located can reasonably take placefirst, because of the current of air kept passing down the throat A and away to the chimney, and, second, because of the trap at the bottom of B, which cuts off all return of air from the vault.

Any kind of deodorizing liquid may be kept in B also, combustible materials may be burned in it, and the smoke and fumes will pass off through the pipe J to the chimney.

It is obvious, if the contents of the feedpipe B are to be allowed at all times to pass freely into the vault D, the cock I must not stand entirely closed, for it controls the airpower by which all admission into the vault,-

after the trap is formed, is determined.

I claim- 1. The air-tight vault D, provided with a I conducting-pipe, B, extending nearly to its bottom, and so constructed that with water it can trap the air, or any desired portion of it, in the upper part of the vault, substantially as and for the purpose herein set forth.

2. The conducting-pipe B, provided with a liquid-trap below, controlling its delivery into the vault D, of which it is a feeder, and at its upper end with a short open throat, A,

and having the airspace 0 and the draft-pipe J, all combined substantially as and for the purpose herein set forth.

3. In combination, the seat A, the liquidtrap conducting-pipe B, and the air-tight vault D, provided with a very small let-off air-pipe, specified, and having a division-plate, E, and H, substantially as and for the purpose herean outlet-cock, F, substantially as and for the in set forth. purpose herein set forth.

4. In combination, the air-tight vault D, having an air let-ofi' passage, controlled by a GEO. R. MOORE, valve or cook, I, and the conducting-pipe B, Witnesses: trapped withliquid, substantially as shown. J. PLANKINTON,

5. The vault D, constructed to be filled, as J 0s. MANUEL.
